First rover bot project!

Hi, i've been searching for this kind of robots and it looks interesting, so i decided to began making one and need some help/advices.
My idea is to have a rover with some sensors (light, distance, temperature, etc), 1 DC motor, 2 or 3 servos... the brain would be a mini-itx pc (has a wireless card) with Arduino Duemilanove (already bought) and a camera too. The rover will be basically running at my home, and in the future i plan to have it automated, so he can go around without human interaction.
